Besides these parts,

vvliieh are old and Well known, the invensuch 17 fol-receiving water from the tube 15 for exhausting at its free open end 18 Within the mouth of the patient adjacent the inlet T111 ofthe hooked pipe 10. a

The tubelttis preferably"secured to the pipe lOflby eonneeting lugs such as 19 and the operation of the detice will be apparent from this description thereof, it being seen thatthe Water entering the branch pipe 14 fromthe tube 15 passes through saidpipe to the pipe 10 and outwardly through the tube 12 exhausting the saliva in the month througlrthe open end 11 ofthe pipe 10; the

saliva l'ia vinb; been diluted or flushed in the mouth by the srnallstreamof Water through the pipe l6 entering the mouth at 18. In the form of myinvention shown in t I providea diluting tube 16" fitted into a groove 20in the curved portion 21 of the hooked pipe 10'. and resting loosely in ing, Qneendoftl1e tube 156' terminates at 185 adjacentthe inletend ilofthe pipe 10 While the opposite end of the diluting tube 16 is detaehabIy conneeted vvith aeurved nipple 3 iarried by i and cernmunicating with the inlet 0;; injectol ipipeli branchfrorn the pipe 10? a at 24, It will be seen that the diluting tube 16" may be readily rernoved from the device bydetachinfg the strap 22 and disconneeting the tubeltif from the nipple 23. The operation isthe 'sanieas heretofore described, the inflowinp; Water through the pipe 141: carrying a'sInall stream through the tube 16' to the mouthof the patient hile the diluted saliva'is ejected through the outlet end 13:

of said pipe 10'.

In Fig. 7 of the drawings, the device is shown the same as in Fig. liexeepting the branch pipe 14" is inwardly bent adjacent its free endand secured by a brace with the hooked pipe 10", While the inlet end 11 thereof is perforated in sprinkler-like formation for receiving saliva and Water into the pipe 10.

said groove or secured therein byspotfiveld lVhile the forms of the device herein set forth are believed to be preferable embodiments of the inv'ention,'it will be understood that minor changes may be made herein W1thout depart ng from the spirit and scope of the invention.

What is claimed as new'is:

1'. A-device of the classldescribed comprising a hooked pipe adapted for resting in the mouth 'of a .pa'tient,1a curved inlet pipe communicating'jtherewith adapted 'I for forcing .fiuid outwardlyfoi the opposite end of said L hooked,pipeandfa diluting tube communieating with thebranch pipe and terminating. adj acent the inlet endof the h ok d i adaptecwor u yin a er to the saliva b ing-ejectedI r r r 2. A deviceof'the describedicomprising a saliva ejector, and. a tube .atta'che'd to th'effiilidj, inlet thereof terminating near and uppiyim' water adjacent the saliva ini let oii the2 device,

3. A device of it hef class described comprising fa hooked salivav -pipe,fa curved branch lsupply ,pip communicating; therewith adaptedfor supplying water, thereto,-a I water supply ,tube attached to ,the ,free end ofthe branch pipe, an outlet tube attached to;theadjacentfin l of hoo p p a a tube for 1 diluting waterfattached to the branchjpipe adapted for receiving 'Water therefrom .and. terminating {adj acent the opposite inlet endiof the hooked pipe.

Ag. Adevice 'of the class described comprising ,a" hooked sal vai pipe, a CLllVBCl branch supply Ipi'pe communicating therewith adapted for supplying water thereto,

. aivvater su'pplyltube 'attached to the free end 7 v of the branch pipe,an outlet: tube attached to-the .a djacent'end of; the hooked pipe, a

"curved, nip'ple 'IeXtending. from the branch pipe,the hooked pipe having, a, peripheral I grooveat'fitscurved portion a tube fitting g within saicl'groovewith one end det'achably connected to said ni'pple and its fopposite out let end terminatingnadjacent thes'aliva in- "'let 'en d of theQhool're d pipe and securing ,fmeansbetween said tnbe and hooked pipe. 5. A saliva ejector comprising a saliva clischarge;pipe,a curved branch pipe communieating" therewith, the adjacent ends of the' bianch and hooke'd pipes being adapted for connection with an inlet and an outlet tube respectively, and a saliva diluting tube carriedby the hooked pipe, adapted for receiving water supply from the branch pipe and having its outlet end adjacent the saliva inlet end of the hooked pipe.

6. A saliva ejector comprising a saliva discharge pipe, a curved branch pipe communicating therewith, the adjacent ends of the branch andhooked pipes being adapted for connection with an inlet and an outlet tube respectively, a curved nipple carried by the branch pipe projecting from the hooked pipe and a relatively small tube detachably' connected to said nipple and carried by the hooked pipe with the outlet end ofthe tube adjacent the inlet end of said hooked pipe.

7. A device of the class described comprising a hooked pipe havin its curved portion provided with a receiving groove, a branch pipe curved similarly to the hooked pipe, communicating with the latter with a portion of the branch pipe parallel with the hooked pipe and the inlet endof the branch pipe positioned adjacent the outlet end otthehooked pipe and a diluting tube detachably secured within said groove in communication with the interior of the branch pipe whereby water from the branch pipe is rection as the curved portion of the branch pipe, a diluting tube mounted in the groove ofthe hooked pipe with its outlet end adjacent the inlet end of the hooked pipe and detachable connections between said tube and supply nipple!v i In testimony whereof I ailix my signature.
